MACHINE FOR WINDING THREAD.

Specification of Letters Patent No. 25,181, dated August 23, 1859'.

To all 'whom 'it may concern.'

Be it known that I, LUoIUs DIMooK, of Hebron, in the county of Tolland and State of Connecticut, have invented a new and Improved Method of Forming the Grooves in the Guides of Machines for Winding Sewing Cotton or Silk or other Thread on Spools; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in which- Figure 1, is a side view of a guide with my improvement, showing its application in combination with a spool on which the thread is being wound. Fig. 2 is a front view of the same. Fig. 3 is a transverse section of the guide. Fig. 4, is a face view of the same. Fig. 5, is a face view of a guide of the old kind, showing its single series of parallel grooves.

Similar letters of reference indicate corresponding parts in the several figures.

In the ordinary method of winding thread on spools it is laid spirally from end to end of the spool in opposite directions alternately by means of traveling guides. The guides ordinarily used to direct the thread on to the spools have cut in their faces by means of revolving burs, a single series of grooves for the purpose of spreading the thread evenly on the spools; but such grooves are always parallel with the planes of revolution of the spools, and consequently they operate in an imperfect manner. My invention consists in a method of cuttin the grooves, by which I substitute for the single series of parallel grooves in each guide, two separate and distinct series of grooves arranged obliquely in opposite directions to the planes of revolution of the spools; the direction of one series corresponding with the direction which the thread has in one of its spiral layers, and the direction of the other series corresponding with the direction which the thread has in the next layer, and the two series being so arranged that neither interferes with the others operation.

To enable others skilled in the art to fully understand and use my invention, I will proceed to describe the manner in which it is to be performed.

My said invention is applicable to winding machines of any of the known forms; and the guides A are, with the exception of the grooves in their faces of the usual construction; and on their being first placed in the machine they have their faces which bear upon the spools perfectly smooth, and only the usual deep cen'tral grooves al, in their ends and upper surfaces for the purpose of guiding the thread on to the spools. The gearing from which the guide carrier derives its motion should be carefully proportioned to make the movement of the guide correspond accurately wi'th the thickness of the thread to be wound. The machine with the guides so applied being in running condition, I place a spool on the winding spindle opposite to each guide, and set the machine in operation to wind on 'to the spool a quantity of thread which has been previously coated or saturated with a mixture of fine emery and oil or some glutinous liquid or which has been saturated with oil or some other liquid anl run through dry flower of emery, or which on or before its arrival at the spool is in some other suit-able manner covered with emery or some other cutting powder. The winding of one spool full of thread in this way will cause the two series of grooves b and c, shown in Fig. 4, to be cut, by the coating of emery or other cutting material on the thread; one series of grooves fitting exactly to the thread wound during the movement of the guide in one vdirection from end to end of the spool, and the other series fitting exactly to the thread wound during the movement of the guide in the opposite direction. These grooves being out by the thread in the winding operation cannot fail to fit exactly the coils of thread of the same size wound by subsequent operations of the machine performed under the same conditions in which the grooves were cut; and hence such grooves cannot fail to spread the thread more evenly than those cut by burs, The grooves cut by my method are also much smoother than those cut by burs, and this peculiarity alone would make them work much easier.

It may be remarked on reference to Fig. 4, 'that the series of grooves b, is in advance of the series c. This is owing to the lateral movement that is given to the guide-carrier to reverse the direction ofthe movement of series of grooves (o, c) having their chanthe guide as the latter arrives at either end nels out on opposite angles, as and for the of the spool. purpose herein shown and described. What I claim as my invention and desire LUCIUS DIMOCK. 5 to secure by Letters Patent, is: Witnesses:

The arrangement and Combination With LUGIUS J. HENAU, Y the guide A, of tWo separate and distinct DAVID N. JONES.
